...early discovery of left-handedness is of prime importance. Fortunately the direction of the spiral of the hair at the back of the head is a good indication of the handedness of any human being. Right-handed people have their hair turn clockwise, left-handed people have it turn counter clockwise...
...Robert Andrews Millikan thinks, but streams of electrons probably originating in Earth's atmosphere. The nearer the Equator, he observed, the less was the rays' intensity. Towards Earth's poles, the intensity increased. Electrons would give such an effect since they would tend to spiral polewards. His readings last week on Hudson Bay, he telegraphed Chicago, again confirmed his view. What special electro-magnetic effect the eclipse had upon his observations...
...Hopkins chemist,G.M. consultant) told them a molecule of water must look like. They took two steel balls of equal weight to represent hydrogen atoms. For the oxygen atom they took a third steel ball weighing 16 times as much as each ''hydrogen atom." They also built spiral springs whose tension in relation to the weight of the three balls resembled the electrical forces which hold a molecule of water together. They joined the "hydrogen" balls to the "oxygen" ball with the springs and set the model shaking by means of a motor. At most speeds they...
Observers last week were already writing Dr. Millikan's answer for him. In his laboratory Millikan had seen cosmic rays penetrate 50 ft. of lead, knock electrons out of atmosphere atoms. Such electrons, Dr. Millikan might say, would naturally spiral toward the poles, knocked out of Earth-atmosphere atoms by cosmic rays still unexplained by Dr. Compton...
